How to use Vue and Element-UI to implement paging display of data tables

Vue is a popular front-end development framework, and Element-UI is a set of UI component libraries based on Vue. The combination of the two It can greatly simplify our process of developing data tables. This article will introduce you to how to use Vue and Element-UI to realize paging display of data tables.

First, we need to introduce the dependencies of Vue and Element-UI into the project. They can be installed via the following command:

npm install vue element-ui

Next, we can introduce the required components and styles in the Vue component:

<template>
  <div>
    <el-table :data="tableData" :pagination="paginationConfig">
      <!-- 这里是表格列的定义 -->
    </el-table>
  </div>
</template>

<script>
import { Table, Pagination } from 'element-ui';

export default {
  components: {
    ElTable: Table,
    ElPagination: Pagination,
  },
  data() {
    return {
      tableData: [], // 表格数据
      paginationConfig: { // 分页配置
        pageSize: 10, // 每页显示条数
        currentPage: 1, // 当前显示页码
        total: 0, // 总条数
      },
    };
  },
  mounted() {
    // 页面加载完成后请求接口获取表格数据
    this.getTableData();
  },
  methods: {
    getTableData() {
      // 这里是实际上请求接口获取表格数据的逻辑
      // 可以使用axios或者其他Ajax库发送请求
      // 请求成功后，将返回的数据保存到tableData中，并设置paginationConfig的total属性
    },
    handleCurrentChange(currentPage) {
      // 切换页码时触发的函数
      this.paginationConfig.currentPage = currentPage;
      this.getTableData(); // 根据新的页码重新请求数据
    },
  },
};
</script>

<style>
/* 这里是Element-UI样式的引入 */
@import "~element-ui/lib/theme-chalk/index.css";
</style>

In the above code, we used Element-UI The el-table and el-pagination components are provided to realize the paging display of data tables. The el-table component is used to display table data, while the el-pagination component is used to display and process paging-related logic.

In data, we define the tableData array to store table data, and the paginationConfig object is used to configure pagination-related attributes.

In the mounted life cycle hook function, we called the getTableData method to obtain table data. This is just an example. In actual applications, data is usually obtained by sending an Ajax request and filled into tableData, and the total attribute of paginationConfig is set to the total number of items.

The handleCurrentChange method is a function triggered when the el-pagination component switches the page number. We update the currentPage property in paginationConfig according to the selected page number, and call the getTableData method to re-obtain the data.

Through the above code examples, we have completed the basic operation of using Vue and Element-UI to implement paging display of data tables. According to actual needs, more columns and functions can be added to meet the requirements of the project. At the same time, Element-UI provides a wealth of components that can be used as needed, such as filters, sorting, etc.
